Hiking in Korea — Best Mountain Trails for Every Level is honestly one of the most exciting topics I get to write about, because after twelve years of lacing up my boots on these peninsular peaks, I am still finding ridgelines and granite summits that completely take my breath away. Korea is a hiker’s paradise in a way that most visitors simply do not expect — about 70 percent of the entire country is mountainous, which means whether you are based in the heart of Seoul or down in the southern port city of Busan, a genuine mountain trail is almost always within subway distance. The mountains here are not just scenery; they are the soul of the country, woven into Korean culture, history, and daily life in a way that makes every hike feel like a story worth telling.
What I love most about hiking in Korea is how democratic it is. On a crisp Saturday morning at Bukhansan in Seoul, you will see a retired grandfather moving with the quiet confidence of someone who has summited a thousand times, a group of university friends in matching windbreakers sharing kimbap at a rocky overlook, and yes — nervous first-timers like many of my friends were on their first trip here, wondering if they have the legs for it. The answer, almost always, is yes. Korea’s trail network spans everything from gentle forest walks to knife-edge granite ridges, and once you understand the system, you will never want to stop coming back.
Best Beginner Mountain Trails — Where to Start Without Regrets
If you are brand new to hiking in Korea and staying in Seoul, Inwangsan (인왕산) is the trail I send every single first-timer to, and they always come back grinning. Take Line 3 to Dongnimmun Station, Exit 2, walk uphill for about ten minutes, and suddenly you are scrambling over smooth white granite boulders with the entire Seoul skyline stretching out behind you — the Han River glittering in the distance, Namsan Tower visible in the haze, the city humming below. The loop trail is only about 4.7 km and takes maybe two hours at a relaxed pace. There is no entry fee. The route winds past the beautifully restored Hanyangdoseong city wall, which dates back to 1396, and in the early morning you might catch shamanist rituals still taking place at Guksadang shrine near the base — one of those only-in-Korea moments that no guidebook can fully prepare you for.
For those wanting a beginner trail outside Seoul, Namsan in Gyeongju is an absolute gem. This gentle mountain sits right in the ancient Silla Kingdom capital and the entire hillside is essentially an open-air museum — stone Buddhas, pagodas, and carved rock faces hidden among the pine trees at every turn. Entry is free, the trails are well-marked in English and Korean, and the highest point is only 494 meters. Pack a kimbap from the GS25 near Gyeongju Station, take your time, and plan for a full half-day. The late afternoon golden light filtering through the pines here is something I still think about years later.
At Inwangsan, avoid the main tourist entry point on weekends and instead start from the back entrance near Suseongdong Valley (수성동 계곡), accessed via a short walk from Gyeongbokgung Station, Line 3, Exit 4. You will skip 80% of the crowds and enter a genuinely quiet forest corridor that most visitors never discover. On hot summer days, the stream here stays refreshingly cold — locals bring their kids to wade in it.
Intermediate Korean Mountain Trails — Earn the View, Feel the Burn
Bukhansan National Park (북한산국립공원) is the mountain that made me fall properly in love with hiking in Korea, and it sits almost impossibly close to central Seoul — you can be on the summit ridge of Baegundae (836.5m) within 90 minutes of leaving Gangnam by subway. Take Line 3 to Gupabal Station, Exit 1, catch Bus 704 to the Bukhansan Ui trailhead, and start climbing. The Baegundae trail is around 9 km round trip with about 700 meters of elevation gain — firmly intermediate, with rope-assisted granite scrambles near the top that get your heart pumping. The entry fee is ₩1,600 (about $1.20), which is genuinely one of the best-value experiences in the entire country. On clear days in autumn, standing on that bare granite peak with the city below and the yellow and red forested ridgelines stretching in every direction is simply stunning. I have done this trail more than thirty times and it never gets old.
For something further afield, Seoraksan National Park (설악산국립공원) in Gangwon Province is where Korean hiking truly announces itself on a world stage
